43DS Windows - Rebedding

[markevans]

Our windows were loose at the bottom when we bought the boat partly due to age/UV and also due to the infamous compression post issue which has now been resolved. The current bond looks like very soft black butyl. Does anyone have experience of doing this? In particular,
how to remove the windows given much of the sealant still works?
which sealant/adhesive to use?
how to press and hold windows in position during cure?

ive seen thevideo that Sikaflex gave at PBO seminar and the post on here about the black paint surround but nothing about the sealant or adhesive.

any advice?

Thanks

Although not full removal, this guide by Brent gives a lot of guidance about preparation etc

Over the years we have gradually had most of the windows re siliconed professionally.
I believe that they use piano wire or similar to ‘saw’ through the old silicon to remove the window but you must be extremely careful as the windows are easily broken if twisted. (Or if you become impatient and try and lift it off before the silicon is cut through).

Replacement of the complex curved ones would be a challenge and we’ve got one ‘new’ window which has a slightly different tint !

The previous owner appears to have removed the protective black paint on the outside strip of each window (aesthetics ?), but this has probably hastened the break down of the silicon.

Edit: the newly siliconed windows were held in place with thin wooden stakes jammed tight using the guardrail wires (with a v cut in this end) and pad against the window. Left this in place for a number days until cured.

We are looking to do ours soon as well and may have to replace a few as they have a lot of spider-webbing and don't look as good as the ones on Manaia. Thanks for the link in the earlier post. Just waiting on approx cost per window from Orakei marine [gulp].

Hi,
autumn is here and I have a lot of projects do to.

Re-sealing deck saloon windows is one of them.
Is there any specific thread in this forum?
I did not find any useful tips.

thank you!

[sailingsvsloth]

Did you end up completing this project? What did you end up using? Our 43DS needs all the windows rebedded

Hi,


no I did not.
Yanmar was the project in autumn and I guess it is time now for the side windows on my DS43.
I took some photos last time I was on the boat and found out that there are small holes in the windows (on the top corner side on both side of each window). Is this original or did someone worked on the windows before I do not know.
But for sure it is there for the screw when pressing the window. 





I'll try to service each window at a time.
Since every window has a gap, I'll take a strong fishing line and go round and cut trough sealant.
Then clean everything and reassemble.
This would be a tricky part.


First I thought I have to move plastic "canopy" above the window to have space to press the window when in place.



But I guess with those small holes I can put a screw and a small piece of board to press it in place.
On the lower side I can do the same but only to screw in the gap between window where later I'll put some sealant.

Applying sealant (Kent, Sika...) could be a mess.
Is there any sealant tape that is good for this job?

My worst fear is to break a window. After all it is 20 y old and always exposed.

I assume that one window will take me at least one day of work.

Hi there

Based on feedback from other boat owners that went through the same process, best is to use the Sika 290D and Sikaflex 295UV 


I was once told to use a cake knife, but I will also give a go to the fishing line



so Saturday is the day, I will post some feedback (unless.... )

Cheers

good luck:)

And please post pictures!

Hi there

OK, I have not started the job yet...there was an issue with the product I got and I am now getting more 209d. But on the interim, I am wondering whether we should replace the screens for new ones. 

Has anyone done this job? what is the life expectancy of the original windows? My boat is from 2002, and I would hate to do the job of re-sealing the windows, and in 2 years having to replace them all...as I hope that by then I will be cruising around

any ideas?


Cheers

[OhWell]

Curious if there is any update on this job?

Hi there

yes, sorry, this year has been……

in order to ripped off all the windows:

• Unscrew the top shading frame, use a long spatula to cut off the silicon 
• The windows are brittle, so with extra care and several spatulas, you can separate the glass from the frame. I started each window from the interior of the boat, working my way around until I could wedge a spatula on the top from the outside
• I found gaps between the window frame and the round trim the windows have inside. The window frame is actually quite low, making t very easy for the water to get in between the fibreglass and the boat interior trim. I fibreglassed all the window frames with the inner window trims to avoid the same situation in the future
• preparing the glass was easy, but the primer is super liquid, so careful there

sadly I cannot find any of the photos I took 


cheers

Hi there

Sadly no, I have not been able to find any of the shots I took
